Most Helpful Positive Review PWS makes some of the best uppers
If you don't own a piston upper you really should. It shoots so much cleaner and the recoil impulse is nice. Plus PWS you have adjustable gas block, comes with charging handle and BCG, really pretty great deal for the times.
Most Helpful Negative Review Its ok, not great
For the price its overrated. I got one to run with an Omega 36m. I have no idea where the "clean running" version is, i didn't get it. I get every bit as much gas in the face on any setting as any of my gas guns. Again its accurate, heavier, and the gas is at least the same if not worse.

amazing upper reciver

by RVO, Verified Owner from CA, United States Written on July 17, 2024
Used it for my first build. Very satisfied with the small recoil, although does run hot after 3-4 mags and also on the heavier side.
Pros:
  • Accurate, consistent, powerful
Cons:
  • Heavy
  • Hot hands
Best Used for:
  • competative shooting
  • range & target shooting
Would recommend: Yes

PWS MK116 Upper

by Brayden Stock, Verified Owner from UT, United States Written on May 24, 2024
Great product. Mounted it to a PSA Sabre lower with a geiselle SSA trigger and B5 furniture. The fitment is fantastic. But it shoots even better. Does not seem to weigh anymore than any of the DI guns I've owned and it shoots significantly better
